I am interested in a vent kit to route some air to the Stable (doghouse)in my W22 Workhorse. In the summer it really gets hot inside and I can feel the heat. I have no problems buying this myself but Workhorse will not sell just the kit. So I thought I will just make my own.

I can find the vent hose no problem but I am having trouble finding a suitable flange or funnel to mount up front to catch the air and route it back through the 3-4" vent hose.

Does anyone have a source for some type of molded plastic flange like this? Basically I need a big funnel with a 3-4" outlet right?

Rotts4u.... You might try Tractor Supply they usually have a lot of items used around the farm and ranches. I was thinking something like an irrigation type of device. Just a thought!

Also, what are you using for the piping? I assume something like aluminum dryer vent piping which is flexible and non-flammable.

It looks like you have to go to the Dealer to have this done? 4 Hours installation = $400,00 plus $143.00. Somewhere around $600.00.

We need to be able to DIY a lot of these things.
The SW FL dealers have raised work rates to $110.00 per hour.

Try the sprinkler & drainage depts. of your favorite home improvement whse. I've seen lots of variations for sub-surface "catch basins". ED

I was thinking that we could use the vent outlets adapters used for heating/ac vents in your home forced air system. I think these come in a variety of sizes in galvanized steel. Paint them black and they should look as good as the factory version.
Where would be the best place to locate the inlet "funnels"?

Personally I wold prefer a molded Polypropylene or polyethelene instead of steel. Less chance of rusting or noise. Not that I dont think your idea will work becuase it is the right shape and has the right outlet as well. I think they need to be mounted either behind the grill or under the bumper.

Either way they need to face forward to get the ram air effect as the coach moves forward.

My reason for it is mainly to cool the doghouse. Perhaps mine gets hotter because I added a different type of sound dampning material and it could be holding in some heat. But in the summer my right foot gets very hot next to the stable.

I figure a stream of air will no nothing but help that. I dont see a downside other than cost /time

The cooling kit dumps air in the vicinity of the center of the exhaust manifold where the manifold gets the hottest. A slight temperature decrease in that particular area has proven to be effective in preventing problems relating to plug wires.

Whether or not there's going to be enough air there to help cool your right foot is yet to be determined.

Like you said, nothing ventured, nothing gained.

In heavy rain, will an excess amount of water on the engine do any thermal damage? These tubes appear to be straight ducts without any water seperators.

In a heavy rain I'd be more concerned about getting water in the air horn than anything else.

My strategy while traveling in a heavy rain is to reduce my speed to 45 mph or so and take it slow and easy.

I had a 94 Flair on a P-30 chasis that ran with a very hot doghouse and was hard on plug wires. I used two 4 inch flexable metal dryer tubes along with two 45 degree 4 inch PVC couplers and a package of 10 inch wire ties. Total cost about $25. Mounted the couplers under the bumper and ran the hoses up to blow along the exhaust manifolds. Took about an hour. Made quite a difference in that I could not keep my foot on the side of the doghouse before and I could place my hand there after. Never had a problem with rain. I am thinking about doing it to my new coach, P-32 Workhorse,just on general principles. Especially after reading these posts.
